Three ways for protein aggregation and the control strategies / 生物工程学报

Protein aggregation is a critical issue in the production of biopharmaceuticals. During protein production, transport and storage, various factors can lead to protein aggregation. With the in-depth study, different ways of protein aggregation and various influencing factors were identified. This includes physical and chemical factors, translation modifications and protein structure. Since protein aggregation exerts major impact on the activity and homogeneity of proteins, it is of great importance to study the ways of protein aggregation and how to control it to obtain high-quality proteins. The review focuses on three ways of protein aggregation, namely 3D domain swapping, salt bridge formation, and oxidative stress, as well as methods to control protein aggregation during protein production, transport and storage. This may facilitate reducing the loss caused by the formation of protein aggregation and improving the purity and homogeneity of protein in research and commercial production.

Effect of "Teddy Bear Simulation Hospital" in cultivating the humanistic care ability for pre-clinical medical students / 中华医学教育探索杂志

The cultivation of medical students' humanistic care ability is one of the most important tasks of medical education. In this study, "Teddy Bear Simulation Hospital" was launched to cultivate humanistic care ability for pre-clinical medical students in the early stage. Firstly, pre-clinical students were organized to visit clinical functional zoning and diagnosis and treatment processes, listen to pediatrician lectures, and understand the diagnosis and treatment process of pediatric patients. Then, students were organized to build a simulated hospital for kids in the kindergarten with reference to the actual situation and carry out simulated diagnosis and treatment. In the process of implementation, students divide the labor, make the plan and take the action independently. After the simulation scenario was created, the kids played the role of parents of the sick children, and their favorite plush toy was pretended to be the sick baby; the medical students played the various roles of the medical staffs in the simulated hospital to carry out various diagnosis and treatment activities in an orderly manner. The results showed that the activity has provided a safe and friendly simulation diagnosis and treatment platform for pre-clinical students. In the interaction with children, the humanistic care ability of the students was significantly improved.

Ultrasensitive quantification of trace amines based on N-phosphorylation labeling chip 2D LC-QQQ/MS / 药物分析学报

Trace amines(TAs)are metabolically related to catecholamine and associated with cancer and neuro-logical disorders.Comprehensive measurement of TAs is essential for understanding pathological pro-cesses and providing proper drug intervention.However,the trace amounts and chemical instability of TAs challenge quantification.Here,diisopropyl phosphite coupled with chip two-dimensional(2D)liquid chromatography tandem triple-quadrupole mass spectrometry(LC-QQQ/MS)was developed to simul-taneously determine TAs and associated metabolites.The results showed that the sensitivities of TAs increased up to 5520 times compared with those using nonderivatized LC-QQQ/MS.This sensitive method was utilized to investigate their alterations in hepatoma cells after treatment with sorafenib.The significantly altered TAs and associated metabolites suggested that phenylalanine and tyrosine metabolic pathways were related to sorafenib treatment in Hep3B cells.This sensitive method has great potential to elucidate the mechanism and diagnose diseases considering that an increasing number of physiological functions of TAs have been discovered in recent decades.

Etiological detection and epidemiological analysis of children with influenza-like illness / 中华检验医学杂志

Objective:To analyze the status and epidemiological characteristics of respiratory virus infection in children with influenza-like illness in outpatient department, and to provide evidence for the prevention and treatment of children in this area.Methods:Nasopharyngeal swab samples were collected from children who attended the fever clinic of The Children′s Hospital, Zhejiang University School of Medicine due to influenza-like illness from July 2021 to March 2022, and six common respiratory virus nucleic acids were detected by reverse transcription-polymerase chain reaction (RT-PCR). The general information of the children was collected and grouped by gender and age (0-<6 months, 6-<12 months, 1-3< year-old, 3-<6 year-old , and ≥6 year-old), and the chi-square test was used for statistical analysis between the groups to explore the epidemic pattern of respiratory viruses.Results:A total of 739 cases (45.9%, 739/1 609) of respiratory viruses were detected from children with influenza-like illness, including 651 cases (40.5%, 651/1 609) of simple infection and 88 cases (5.5%, 88/1 609) of multiple infections. Respiratory syncytial virus (RSV) was detected in 18.6% (300/1 609), followed by influenza B virus (FluB) in 11.9% (192/1 609), adenovirus (ADV) in 8.3% (134/1 609), parainfluenza virus type 3 (PIV-3) in 7.6% (123/1 609), parainfluenza virus type 1 (PIV-1) in 4.9% (79/1 609), and influenza A virus (FluA) in 0.4% (6/1 609). Multiple infections including double or triple infections, with 81(92.0%, 81/88) cases of double infection and the most common being ADV+RSV (22.7%, 20/88) and 7 (8.0%, 7/88) cases of triple infection. There was a significant difference in the virus detection rate between the age groups (χ2=17.078, P=0.002), with the highest virus detection rate in the 3-<6 years of age group (49.7%, 286/575). Among the detection of simple infection, FluB had the highest detection rate in the ≥ 6 years of age group (26.6%, 98/369), and RSV and PIV-1 had the highest detection rate in the 3-<6 years of age group (20.0%, 115/575 and 5.9%, 34/575). The total monthly virus detection rate increased from 26.8% (37/138) in July to 63.0% (58/92) in January, and decreased to 46.1% (106/230) and 26.8% (37/138) in February and March. The detection rate of RSV was the highest from August to November, the detection rate of FluB was the highest from December to March, the detection rate of ADV increased in December and January, and the detection rate of PIV-3 increased from October to December; the detection rate of PIV-1 did not fluctuate significantly, and FluA was sporadically detected. Conclusions:RSV is the main respiratory virus in children with influenza-like illness. Most respiratory viruses are present as single infections. Multiple infections are more common in double infections. FluB, RSV and PIV-1 infections showed certain age distribution characteristics, especially in children over 3 years of age. The epidemic characteristics of respiratory virus infection show that the epidemic gradually peaks from summer to autumn and winter, and turns into an epidemic decline in spring. RSV was relatively prevalent in autumn, FluB was prevalent in winter and spring, ADV and PIV-3 were prevalent to varying degrees in winter, PIV-1 continued to circulate at a low level, and FluA did not present epidemic characteristics.

Evolution and Connotations of "Prohibition"， "Contraindication"， or "Use with Caution" in Chinese Materia Medica / 中国实验方剂学杂志

This study systematically combed and analyzed the use of such terms as "prohibition"， "contraindication"， and "use with caution" in ancient Chinese books on materia medica and prescriptions， Pharmacopoeia of the People's Republic of China（《中华人民共和国药典》）， and teaching materials and monographs of Chinese materia medica by means of hermeneutics， commentariology， textology， and data mining， and explored the historical evolution and conceptual connotations of "prohibition"， "contraindication"， and "use with caution" in Chinese materia medica， so as to provide reference for standardizing their understandings and clinical reasonable medication. The "prohibition"， "contraindication"， and "use with caution" of Chinese materia medica were first proposed in the period of pre-Qin and Han dynasties. "Prohibition" and "contraindication" were separately developed in the Sui， Tang， and Five dynasties and Song， Jin， and Yuan dynasties and have been widely used since the Ming and Qing dynasties. The "use with caution" becomes popular rapidly in modern times and is often present in clinical medication together with "prohibition" and "contraindication". "Prohibition" basically means strictly prohibited and "contraindication" means to avoid as much as possible. The terms "prohibition"， "contraindication"， and "use with caution" have experienced evolution from the pre-Qin period to modern times， and they are used to describe the degree of restriction on drug use（"prohibition" > " contraindication" > "use with caution"）.

Research status of acetabular reconstruction in Crowe type Ⅱ and Ⅲ developmental dysplasia of the hip / 中国骨伤

Developmental dysplasia of the hip (DDH) is a major cause of hip arthritis and ultimately total hip arthroplasty. Due to the dysplastic acetabulum, how to place the acetabular cup becomes a challenge in acetabular reconstruction for such patients. Especially in the acetabula classified as Crowe typeⅡand type Ⅲ, the dislocation of the femoral head causes bone defects above the true acetabulum, which will affect the stability of the acetabular cup when the acetabular reconstruction is performed at the true acetabulum. Many acetabular reconstruction methods such as bone grafting, the use of small acetabular cups, socket medialization technique, and high hip center technique are used to increase the host bone coverage of the cup. However, each method has its own shortcomings that can not be ignored so that there is no unified conclusion on the acetabular reconstruction methods for Crowe typeⅡand type Ⅲ hip dysplasia. This article summarized and evaluated various reconstruction methods in combination with the acetabular morphology of DDH, and put forward the research direction in the future.

Development of novel-nanobody-based lateral-flow immunochromatographic strip test for rapid detection of recombinant human interferon α2b / 药物分析学报

Recombinant human interferon α2b(rhIFNα2b)is widely used as an antiviral therapy agent for the treatment of hepatitis B and hepatitis C.The current identification test for rhIFNα2b is complex.In this study,an anti-rhIFNα2b nanobody was discovered and used for the development of a rapid lateral flow strip for the identification of rhIFNα2b.RhIFNα2b was used to immunize an alpaca,which established a phage nanobody library.After five steps of enrichment,the nanobody I22,which specifically bound rhIFNα2b,was isolated and inserted into the prokaryotic expression vector pET28a.After subsequent purification,the physicochemical properties of the nanobody were determined.A semiquantitative detection and rapid identification assay of rhIFNα2b was developed using this novel nanobody.To develop a rapid test,the nanobody I22 was coupled with a colloidal gold to produce lateral-flow test strips.The developed rhIFNα2b detection assay had a limit of detection of 1 μg/mL.The isolation of I22 and successful construction of a lateral-flow immunochromatographic test strip demonstrated the feasibility of performing ligand-binding assays on a lateral-flow test strip using recombinant protein products.The principle of this novel assay is generally applicable for the rapid testing of other com-mercial products,with a great potential for routine use in detecting counterfeit recombinant protein products.

Evaluation Elements of Clinical 'Prohibition' 'Contraindication'， or 'Use with Caution' in Chinese Medicine Based on Ancient and Modern Literature / 中国实验方剂学杂志

In view of the current controversy in the clinical evaluation of the terms of 'prohibition' 'contraindication'， and 'use with caution'， the present study summarized their evaluation elements to provide references for the classification of 'prohibition' 'contraindication'， and 'use with caution' and clinical rational medication of drugs. Based on the ancient and modern representative traditional Chinese medicine （TCM） literature， such as the records on herbal medicines and prescriptions， medical classics， pharmacopoeia， clinical monographs， and papers， this study proposed the evaluation elements and the underlying ideas of 'prohibition' 'contraindication'， and 'use with caution' around the risks and benefits of medication. The results indicate that the evaluation elements of 'prohibition' 'contraindication'， and 'use with caution' include TCM property，syndrome，symptom， TCM compatibility，dosage，and treatment course. When evaluating 'prohibition' 'contraindication'， and 'use with caution' of TCM under specific conditions of medication，we can determine the properties of prohibited or contraindicated drugs prior to figuring out the differences in 'prohibition' 'contraindication'， and 'use with caution'. It is feasible to evaluate the clinical 'prohibition' 'contraindication'， and 'use with caution' in TCM from Chinese medicine， body， and the clinical medication， which are correlated with each other in the practice implementation.

Despite the effectiveness of anticonvulsants, antidepressants, and lidocaine patches in reducing PHN, many patients still face intractable pain disorders.In this randomized controlled study, we evaluated whether hydromorphone through intravenous patient-controlled analgesia (IV PCA) was effective in relieving PHN. @*Methods@#Patients with PHN were randomly divided into two groups, one group received oral pregabalin with IV normal saline, another group received oral pregabalin with additional IV PCA hydromorphone for two weeks. Efficacy was evaluated at 1, 4, and 12 weeks after the end of the treatments. @*Results@#Two hundred and one patients were followed up for 12 weeks. After treatment, numerical rating scale (NRS) score of patients in the hydromorphone group was significantly lower than that of the control group, and the difference of NRS scores between the two groups was statistically significant at 4 and 12 weeks after treatment. The frequency of breakthrough pain in the hydromorphone group was significantly lower than that in the control group 1 and 4 weeks after treatment.After treatment, the quality of sleep in the hydromorphone group was significantly improved compared with the control group. The most common adverse reactions in the hydromorphone group were dizziness and nausea, with no significant respiratory depression. @*Conclusions@#IV PCA hydromorphone combined with oral pregabalin provides superior pain relief in patients with PHN, which is worthy of clinical application and promotion.

Intravenous patient-controlled analgesia hydromorphone combined with pregabalin for the treatment of postherpetic neuralgia: a multicenter, randomized controlled study

Background@#Postherpetic neuralgia (PHN) is the most common complication of acute herpes zoster. The treatment of PHN remains a challenge for clinical pain management. Despite the effectiveness of anticonvulsants, antidepressants, and lidocaine patches in reducing PHN, many patients still face intractable pain disorders.In this randomized controlled study, we evaluated whether hydromorphone through intravenous patient-controlled analgesia (IV PCA) was effective in relieving PHN. @*Methods@#Patients with PHN were randomly divided into two groups, one group received oral pregabalin with IV normal saline, another group received oral pregabalin with additional IV PCA hydromorphone for two weeks. Efficacy was evaluated at 1, 4, and 12 weeks after the end of the treatments. @*Results@#Two hundred and one patients were followed up for 12 weeks. After treatment, numerical rating scale (NRS) score of patients in the hydromorphone group was significantly lower than that of the control group, and the difference of NRS scores between the two groups was statistically significant at 4 and 12 weeks after treatment. The frequency of breakthrough pain in the hydromorphone group was significantly lower than that in the control group 1 and 4 weeks after treatment.After treatment, the quality of sleep in the hydromorphone group was significantly improved compared with the control group.
